Pediatric emergency physicians are experienced in the diagnosis and treatment of all types of emergencies in infants, children, teens, and young adults. They usually treat the following types of emergencies:
Solar irradiance. It's reasonable to assume that changes in the sun's energy output would cause the climate to change, since the sun is the fundamental source of energy that drives our climate system. Indeed, studies show that solar variability has played a role in past climate changes.
Human causes. Climate change can also be caused by human activities, such as the burning of fossil fuels and the conversion of land for forestry and agriculture. Since the beginning of the Industrial Revolution, these human influences on the climate system have increased substantially.
